Does such an argument actually exist?  My experience has been that
stable-maint folks are very accepting of help, and that it's relatively
easy for core reviewers with an interest in stable branch maintenance to
offer their services and become stable-maint core:

Who is ignoring stable branches?  This sounds like a project specific
failing to me, as all experienced core reviewers should consider offering
their services to help with stable-maint activity.

I don't personally see any reason why the *entire* project core team has to
do this, but a subset of them should feel compelled to participate in the
stable-maint process, if they have sufficient time, interest and historical
context, it's not "some other team" IMO.

Also, contributors should be more actively encouraged to propose their
bugfixes as backports to stable branches themselves, instead of relying on
$someone_else to do it.
